The Gearmotor is the vertical axis form, the first stage input shaft is the bevel gear shaft worm Gearmotor, and the more serious stress concentration occurs at the transition shoulder of the bevel gear bearing bearing. The Gearmotor is hardened , The Gearmotor input shaft diameter is smaller, although the calculation of strength through the shaft itself is very fine, the same in the shaft diameter changes in stress concentration and fatigue damage; worm gear Gearmotor input shaft heat treatment quality failure;

Pay attention to the daily maintenance of the Gearmotor, do not only use, no maintenance, which is the use of the Gearmotor, the good equipment, not maintenance, his life should be reduced by at least one-third. Therefore, daily maintenance is particularly important, the daily maintenance of the Gearmotor, including: the use of oil replacement, check the installation base, seals, transmission shafts are normal, in addition to the shell and other important parts of the maintenance.

The output shaft of the gear unit also has a break or bend, which is the same as the cause of the drive motor. But the output of the Gearmotor is to drive the motor output and reduction ratio of the product, relative to the motor in terms of greater output, so the Gearmotor output shaft is more likely to be broken. Therefore, the user in the use of Gearmotor, the assembly of its output concentric assurance should also pay great attention! Two Gearmotor output is too small to break the axis of the problem

Second, in the process of acceleration and deceleration, the torque output of the Gearmotor output shaft is twice as large as its rated output torque, and this acceleration and deceleration are too frequent, The Taking into account the emergence of this situation less, so here is no further introduction.

If the error of the Gearmotor concentricity is large, the radial force increases the motor output shaft temperature, its metal structure is constantly destroyed, and finally the radial force will exceed the motor output shaft can bear the radial force, and finally Causing the drive motor output shaft to break. When the greater the error of concentricity, the shorter the time the motor output shaft is broken. While the drive motor output shaft is broken, the Gearmotor input also receives radial forces from the motor. If the radial force exceeds the maximum radial load that the two can bear, the result is Resulting in deformation of the Gearmotor input or even fracture. Therefore, in the assembly to ensure that concentricity is essential!
